Frigid? I'll show you!

I am a 34 year old married woman and I am fed up of my husband saying that I am boring or frigid over the few past months as I simply refuse to watch porn with him. My fantasy is to prove him wrong in a shocking manner by sleeping with another man in our bedroom and record it all. I would then leave the recording on his desktop before I go to work and happen to leave my phone at home too so he could not contact me...he would obviously watch it whilst I was away...lets see if he would call me boring or frigid when I got home from work...
